AMBROSE A. HASTINGS, OF NEWARK, NEW JERSEY, ASSIGNOR OF ONE- TENTH TO WILLIAM DIXON, OF SAME PLACE. V

LAMP.

SPECIFICATION forming part of Letters Patent No. 247,822, dated October .4, 1881.

Application filed February 21, 1881.

To all whom it may concern:

Be itk'nown that I, AMBROSE A. HASTINGS, of Newark, in the county of Essex and State of New Jersey, have invented a new Improvement in Lamps, of which the following is a full, clear, and exact description.

Figure 1 is a sectional side elevation of my improvement. Fig. 2 is a sectional plan view of the same, taken through thelineww, Fig. 1. Fig. 3 is a side elevation of a part of the same.

The object of this invention is to improve the light-giving qualities of lamps and secure greater safety in their use.

The invention consists in constructing the oil-chamber and the globe of a lamp in one piece; also, in the com bi'natioinwith the grooved neck ofthe lamp and with the burner-collar having flange, of the rubber packing-ring and the clamping-plate and its nut, whereby the burner-collar will be securely connected with the lamp; also, in the combination, with the stationary part'of the globe having recesses in the outer surface of its up per part, and the movable part of the globe having recesses in the outer surface of its lower part, of the springbutton and its pivoting-screw, whereby the said stationary and movable parts of the globe are securely connected; and, also, in the combination, with the stationary part of the globe and the clamping-plate, ofthe key and its bearing and spiral spring, whereby the Wick can be adjusted without interfering with the removal of the burner, as will be hereinafter fully described.

A represents the oil-chamber of a lamp, the top opening of which is designed to be alittle larger than the ordinary top opening of a lamp.

B is the lower part of the globe, which is made solid with the oil-chamber or body A of the lamp. The partB of the globe may be half a globe, or more or less than half a globe, as may be desired.

In the lower partof the globe B are formed openings 0 to admit air to support combustion. In the inner surface of the neck of the lamp is formed .a half-round groove, D, to receive a packing-ring, E, of rubber or other suitable material.

F is the lamp-burner, which is screwed into a collar, G, in the ordinary manner.

(No model.)

Upon the lower end of the collar G is formed a ring-flange, H, of such a size that it can be passed in and out through the neck of the lamp. The outer edge of the flange H is inclined, flared, or curved downward to fit against the lower inner part of the'packing-ring E.

I. is a ring-plate that fits upon the collar G, and rests and fits upon the inner surface ofthe lower part of the globeB and upon the upper inner part of the packing-ring E. The ringplate I is held down to its place by a nut or screw-collar, J, screwed upon the outer surface of the upper part ofthe collar G. E With this construction, by screwing down the nut J the packing-ring E will be compressed between the flange H and the plate I, and will be firmly forced into the groove D, so as to hold the burner-collar G securely, and allow the burnerv F to be screwed in and out, as required. The

, plate I is finely perforated over the openings O, to allow the air to pass in freely.

In the outer surface of the upper part ofthe globe B are formed recesses K, to receive the coiled ends of the springs L, which are pivoted in the said recesses by screws M, formed upon or attached to the ends of the said springs, passing through the outer coils of the springs and through the globe B, and having nuts screwed upon their inner ends.

The outer or free ends of the springs L have knobs or points formed upon or attached to them, to enter recesses N in the outer surface of the upper or detachable part, 0, of the globe, and thus hold the said part 0 securely in place. The lower edge of the upper part, 0, of the globe overlaps the upper edge of the lower part, B, as shown in Fig. 1, so as to give the said part 0 a firm seat. The upper part,

top for the escape of heated air and the gaseous products of combustion, which opening may be surrounded by a flange or chimney, P, formed solid with the said part 0.

Q is the stem that carries the spur-wheels that raise and lower the wick. The stem Q is made short, and one or both of its ends are squared to fit into a similarly-shaped socket in the inner end of the key R, which passes through one of the holes 0 in the globe B, and through a bearing, S, formed'upon or attached to the 'O, of the globe has an opening formed in its I plate I. The key R is pressed outward, and thus held out of contact with the stem Q, by a spiral spring, T, placed within the bearing S, that carries the said key. The key R has a button or other suitable handle attached to its outer end for convenience in operating it. With this construction the burner F can be readily screwed into and out of its collar With this construction, also, when the lampwiek is to be adjusted the key is pushed inward to cause its inner end to engage with the stem Q, so that the wick can be adjusted by turning the said key It.

A key, B, may be placed at each side of the globe B, so that the wick can be adjusted from either side of the lamp.

The oil-chamber A may be provided with a filling-aperture, U, or it may be filled through its neck by taking out the burner F.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. Alamp constructed, substantially ashereinshown and described, with a globe, 13, formed in one piece with the ditch-amber A, as set forth.

2. In a lamp, the combination, with the grooved neck of the lamp, and with the burnercollar G, having flange H, of the rubber packing-ring E, the clamping-plate I, and the nut J, substantially as herein shown and described, whereby the burner-collar will be securely connected with the lamp, as set forth.

3. In a lamp, the combination, with the stationary part B of the globe, having recesses K, and the separate part 0, having recesses N, of the spring-buttons L and their pivoting-screws M, substan tiallyas herein shown and described, whereby the separate part of the globe can be readily removed and will be securely held, as set forth.

4. In a lamp, the combination, with the stationary part B of the globe and the clampingplate I, of the key R, the bearing S, and the spiral spring '1, substantially as herein shown and described, whereby the wick can be adjusted without interfering with the removal of the burner, as set forth.

AMBROSE A. HASTINGS.
